Our Testimonials

★★★★★

Players get multiple cuts without rattling their hands.  The balls are extremely durable.  We use them for breaking balls, and they are very true.  Curveballs, right-handed sliders, left-handed sliders, you name it.

These balls are the best thing to come around since I have been coaching. ProLine Balls have given our players so much confidence at the plate.

My hitters love The Proline Balls! Velocity and breaking ball training help my guys slow the game down when it counts. If you can beat these balls, you can beat anyone. Huge confidence booster plus, no hand injuries.

The Proline balls are great for all aspects of training. From the bat to the glove, PLB has it covered! They make it easy to manipulate what you need to work on without having to worry about the wear and tear to your glove or bat!

Balls have been awesome. Definitely helping the kids get use to higher velocity and seeing some movement as well without worrying about getting hit.

Finding quality resistance bands and weighted balls for training / rehab has always been an issue, until now. ProLine resistance bands havre proper resistance and durability needed to endure our daily usage. The weighted balls provide the perfect weight range to improve acceleration /deceleration of the arm to build efficient arm path and shoulder mobility”.

We love ProLine Balls! Great for training high velocity! Great for hitting with wood bats or heavy bats. And incredibly durable!
